A team of astronomers from MIT and other institutions have detected a “sun-like star gobbling up a planet and belching out a blast of light and energy,” reports Leah Crane for New Scientist. “In the past, all of the evidence that we’ve had of stars eating planets is from looking at stars that have done that hundreds of thousands of years ago,” says postdoc Kishalay De. “But we have never caught a star red-handed eating a planet.”
AP reporter Marcia Dunn writes that scientists from MIT, Harvard, Caltech and elsewhere have “caught a star in the act of swallowing a planet — not just a nibble or bite, but one big gulp.” Dunn explains that: “Massachusetts Institute of Technology researcher Kishalay De spotted the luminous outburst in 2020 while reviewing sky scans taken by the California Institute of Technology’s Palomar Observatory. It took additional observations and data-crunching to unravel the mystery: Instead of a star gobbling up its companion star, this one had devoured its planet.”
Astronomers from MIT, Harvard, Caltech and other institutions have, for the first time, captured the moment when a star swallows a nearby planet, reports Ian Sample for The Guardian. “Like a lot of discoveries in science, this happened to be an accidental discovery that really opened our eyes to a new type of phenomenon,” explains postdoctoral scholar Kishalay De. “This is going to be the final fate of Earth.”
New York Times reporter Dennis Overbye spotlights how scientists have captured a new image of the black hole at the center of the Messier 87 galaxy, bringing visibility to the “cooler outer regions of the black hole’s fiery accretion disk.” Research Scientist Kazunori Akiyama explained, “I’m really excited to see this result, because now we have a new tool to capture what is surrounding the famous E.H.T.’s black hole. We will be able to film how the matter falls into a black hole and eventually manages to escape.”
Scientists have captured a new image of M87*, the black hole at the center of the Messier 87 galaxy, showing the “launching point of a colossal jet of high-energy particles shooting outward into space,” reports Will Dunham for Reuters. "This is what astronomers and astrophysicists have been wanting to see for more than half a century," explains Research Scientist Kazunori Akiyama. "This is the dawn of an exciting new era."
A team of researchers have produced a new image of the black hole at the center of galaxy Messier 87, reports Isaac Schultz for Gizmodo. “The new image shows a larger ring of accreted material than the first images of the black hole indicated. At the center of the ring is the black hole—or its ‘shadow,’ as scientists say, because the black hole itself cannot be imaged,” writes Schultz.
An international team of astronomers, including MIT scientists, have captured new images of black hole in a nearby galaxy, reports Jon Kelvey for Popular Science. “Going forward, astronomers plan to observe the black hole at other wavelengths to highlight different parts and layers of its structure, and better understand how such cosmic behemoths form at the hearts of galaxies and contribute to galactic evolution,” writes Kelvey.
Prof. John Gabrieli speaks with GBH host Jeremy Siegel about his research showing that standard autism diagnostic tests often prevent women and girls from receiving proper diagnosis and proper treatment. “It’s only in recent years that we've understood that autism can be expressed quite differently in females,” says Gabrieli. “And we need to know that so they get the right kind of help.”
Research Scientist Kazunori Akiyama speaks with Guardian reporter Hannah Delvin about the first image of a jet being launched from edge of black hole. “This is the first image where we are able to pin down where the ring is, relative to the powerful jet escaping out of the central black hole,” says Akiyama. ““Now we can start to address questions such as how particles are accelerated and heated, and many other mysteries around the black hole, more deeply.”
Writing for The Hill, Prof. David Rand and research affiliate Ben Tappin examine their recent study that finds “Americans are more receptive to information that challenges their party leader’s position than we — and most others — had previously thought.” Rand and Tappin emphasize that “our identities, motivations and values are not (yet) reducible to party loyalty, and arguments and evidence can still change people’s minds — even if only a little bit at a time.”
Researchers from MIT and elsewhere published a paper exploring the abilities of language models and how they differ from those of humans, reports Will Knight for Wired. Prof. Josh Tenenbaum says “GPT-4 is remarkable but quite different from human intelligence in a number of ways,” writes Knight. “It lacks the kind of motivation that is crucial to the human mind.”
Quanta Magazine reporter Jordana Cepelewicz spotlights graduate students Ashwin Sah and Mehtaab Sawhney for their work proving the existence of special objects called “subspace designs.” Sah and Sawhney have “proved the existence of objects whose existence is not at all obvious,” said Prof. David Conlon of the California Institute of Technology. “They’re producing high-quality research at a rate where I can’t even blink.”
Virginia Norwood ’47, an aerospace pioneer who designed and championed the scanner used to map and study the earth from space, has died at 96, reports Dylan Loeb McClain for The New York Times. Using her invention, the Landsat Satellite program has been able to capture images of the planet that provide “powerful visual evidence of climate change, deforestation and other shifts affecting the planet’s well-being,” writes McClain.
Researchers from MIT and else have documented the destructive power of hand magnets, a technique used for identifying meteorites, reports Zack Savitsky for Science. “When brought within a few centimeters of a rock, the researchers found, the magnets overwrite vestigial fields contained in iron-based minerals such as magnetite and reset them to the higher strength and orientation of the magnet,” writes Savitsky.
Prof. Tanja Bosak speaks with Scientific American reporter Jonathan O’Callaghan about the possibility that the soil samples collected by NASA’s Perseverance Rover on Mars could contain evidence of ancient Martian life.
